	This guide documents fault diagnosis for the '''[[IBM 5120]] Computing System''' (also designated IBM 5110 Model 3). The 5120 inherits the PALM processor and APL / BASIC ROM environment from the [[IBM 5100]] and [[IBM 5110]], so much of the troubleshooting practice translates directly. The 5120's two built-in 8-inch floppy drives, larger 9-inch CRT, and detached keyboard add their own diagnostic surface.
